BOTTEE-FINISHER.

SPECIFICATION forming part of Letters Patent No. 654,768, dated July 31, 1900.

Application led May 3, 1900. Serial No. 15,329. i (No model.)

T0 all whom if may concern:

Be it known that I, JAMES M. THOBURN, a citizen of the United States, residing at Oanton, in the county of Stark and State of Ohio, have invented certain new and useful Improvemen ts in BottleFinishers; and I do hereby declare that the following is a full, clear, and exact description of-thesame, reference being had to the annexed drawings, making a part of this specification, and to the gures of reference marked thereon, in Which- Figure 1 isa perspective view showing the different parts properly assembled. Fig. 2 is a horizontal section. Fig. 3 is an enlarged view showing a portion of the power or driving shaft, also showing the movable blade designed for forming the export part of the bottle.

The present invention has relation to machines for finishing the necks of bottles; and

it consists in the different parts and combi.

nation of parts hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate cor: responding parts in allthe figures of the drawings.

In the accompanying drawings, 1 represents the base, which may be substantially of the form shown, or it may be of any other desired form, inasmuch as its only object is to provide a suppOrt or bench for the machine proper. p

To the base 1 are securely attached the standards 2, to the top or upper ends of which is properly joined the driving-shaft 3, which driving-shaft is provided with the pulley 4, around which pulley is located the belt, which leads to any source of power.

To the working end of the shaft 3 is securely attached in any convenient'and. well-known manner the disk 4a, which disk is provided with the reciprocating radial bars 5, which bars are located in grooves or waysl 6, formed in the disk. The inner ends of the bars 5 are each provided with the right-angled portions 7, the inner faces of which are concave and are soformed for the purpose of properly fitting around the outer periphery of `the neck of the bottle.V

Within the working end of the power-shaft 3 is located the stem or shank 8 of the blade 9, which stemor shank is provided with the 15, said collar being provided upon one side with the operating-lever 16 and upon the opposite side with the arm 17, which arm is pivotally connected to the bar 1S or its equivalent. It will be understood that as the lever 16 is moved back and forth it will impart a' reciprocating movement to the sleeve 12, which'reciprocating movement is for the purpose hereinafter described.

To the sliding sleeve 12 are pivotally attached the links 19, which links are pivotally connected at their opposite ends to the links 20, said links 2O being pivoted to the sliding bars 5.

It will be understood that as-the lever 16 is moved toward the disk 4a the links 19 Will be carried with said sleeve, by which movement the links 2O will be forced toward the disk 4iL at their lower ends, thereby causing the bars 5 to move away from a common center by reason of the intermediate links 21, said inter-A mediate links 21 being pivotally connected at a common center with the pivotal connection wit-h the links 19 and 20.

It will be understood that as the links 21 rock or move upon their fixed pivotal points their free ends will describe the arc of a circle as the sleeve l2 is moved back and forth, by which .arrangement a reciprocating movement will beF imparted to the bars 5, and thereby carry the concave angle portion 7 to and from a common center, thereby providing a means for adjusting the right-angle flanges or jaws to different-sized necks.

For the purpose of producing a bottle the outer end of the neck portion of which is provided With a passage having a diameter less than the diameter of the inner portion or that portion next to the bottle proper the blade 9 is provided, which blade when in its normal position is in practical alinement with the power-shaft.

In use when it is desired to finish the neck IOC IOv

of a bottle the bottle while in a hot `state is placed over the blade 9, after which the bars 5, together with their flanges or jaws, are brought toward each other until they comein contact with the outer periphery of the neck. As the bars 5, together with the lianges 7, are brought toward a common center the blade 9, by reason of its inclined shaft 10, resting upon the inclined lever, will be moved laterally, as illustrated in the dotted line, Fig. 3, by which arrangement a passage of greater diameter is formed in the neck of the bottle that comes in contact with the blade after said blade has,

.power-shaft 3, and to the endof the shank 8.

It will be understood that the movement of the link 2l will impart a rocking movement` to the link 23 through the link 22, by which arrangement the blade 9 is moved back and forth, and as the blade is moved outward it will be moved laterally, thereby throwing the 'rocking edge of said blade farther away from a commoncenter, by which arrangement the inner portion of a neck when finished is provided with a passage having alarger diameter.

The object and purpose of providing the neck of a bottle with different diameters and the larger diameter located in the inner portion of the neck are to allow the cork or stopper to expand at its inner end, thereby preventing any accidental displacement thereof.

'It will be understood that for the purpose Y of supplying air the power-shaft should. be formed hollow, as illustrated, the air being supplied in the usual manner.'

I-Iaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y Y l. The combination of a power-shaft, a disk connected thereto reciprocating radial bars connected to the disk and provided with rightangled portions,a blade provided with a shank having an inclined edge, an inclined face formed upon the power-shaft and means for imparting reciprocating movement to the bars and to the blade, substantially as and for the purpose specified. f

2. The combination of a power-shaft, a disk connected thereto, and rotatable therewith, bars carried by the disk, a sleeve mounted on the shaft, a blade on the shaft provided with a shank, links pivotedto the sleeve and connecting bars and blade and means for moving theblade laterally at a time when said blade is moved longitudinally, substantially as and for the purpose speciied.

3.' The combination offl a power-shaft, adisk provided with reciprocating bars having lflanges at their inner ends, said power-shaft provided with a blade, and means for imparting longitudinal and lateral movement to the blade, substantially as and for the purpose specified.

In testimony that I claim the above I have hereuntosubscribed my name in the presence of two Witnesses.
